Health Sciences North is asking Pokémon Go players to refrain from playing on hospital property.
"We admit patients, not Pokémon," said a post on HSN's Facebook page.
"Please respect our patients and families who come here to receive care We believe in play and encourage users to take time out from #PokémonGo and enjoy other playful activities that promote healthy living. Walking or cycling just 30 minutes each day can help reduce the risk of preventable illnesses such as obesity, diabetes and heart disease.
Be safe, and please respect the privacy of our patients.”
HSN isn't the only hospital to say "no" to Pokémon Go. Sick Kids in Toronto is also asking trainers to play elsewhere.
A group in Montreal tried to organize a lure party near the local children's hospital, but were also turned away.
"Dropping lures around the hospital may result in great frustration amongst our patients since many of them are very ill and/or cannot leave their rooms," Montreal Children's Hospital told MTLBlog.
Instead, the hospital is encouraging trainers to drop lures near pediatric rehabilitation centres such as the Ronald McDonald House.
"Dropping lures near these places will go a long way to put a smile on a sick child’s face."
Meanwhile, the C.S. Mott Children’s Hospital in Michigan, is using the app as a tool to get sick patients out of their rooms and interacting with fellow patients and hospital staff.
